执行2次我是不知道了，可能是表单那里递交了2次吧，，
你的代码给的不全
但是执行完nsert（）方法后你把session给关了。。
if (list.size()> 0) { //存在该信息
ret = 2;
} else {
session=MySession.openSession(); //打开Session
try {
tx = session.beginTransaction();
这里的的list查出来有值，而你有调用session的开启事务，这时的session是关闭的，包出session is closed！
userAdd 被调用两次，所以System.out.println("q1");执行了两次- -
